SAFEGUARD LIFE AND TELEPHoNE ATTACHMENT.

Specification. of Letters Patent.

Application filed February 27, 1913. Serial No. 751,005.

To a'zc/zom- 'it may concern .f

/'- .Be it known that I, Istrien E.'ROSENTHAL, a citizen of Argenta, in the county of Pulaski and State of Arkansas, have invented a new and useful Improvement' in Safeguard Life and Telephone Attachments, of which the following is a specication.

i M v .invention is an improvement in safe guard life and telephone attachments, and has for its object the provision of mechanism for installation in homes, hospitals, factories, ware-houses. and thelike, for proin case of tire. wherein means is provided for automatically sounding an alarm and at a time before the `lire has gained too) great a headvfav to be extinguished.

In the drawingsz-Figure l is a per of the improved attachment, Fig. f! isa section on the line 2-2 of Fig. 1. Fig. a section on the line 3-3 cf Fig. 2. Fit. 1 is a perspective view of the signal device with the parts separated, Fig. 5' is a transverse section of the fuse attachment, 'and Fig. 6 is a section on the line G- of Fig. 5.

The present embodiment olf the invention is adapted to be arrangednear a `telephone transmitter 1, immediately below therhook 2. that supports the receiver 3, and the'said` Idevice comprises a. casing' 4, having at its rear an upward extension in which is`arranged a guidewav -6 at therear thereof, the said guideivav being reinforced by achannel plate*V T. vwhosel side-` edges are laterally flanged at S. and' are seated in counter-sinks,

and secured tc.- the extension and the casing bv screws 9. or the like. The said guideway isuattlie rear of the casing and extends the fullheight of the extension and a portion of the height of the body of the casing. slide or sliding member 1G is mounted in tbel guidewav. and alv approximately the center of the guidewav the reinforcement 7 providedivith a lug 11. extending into the gnidevvav. the said .lug being rectangular in cross section and having a ing 1Q. The sliding member 10 is longi Vtudinallv slotted at13 and lll, the latter slot or recess receiving the lug 11. Above thel slot or recess meml'ier is recessed at its opposite side edges 'zndicatedfat 14'. and just above the said recesses and above the upper end of the bar tbc slidingr member provided with a cross bar 15, connected to the sliding member 'by `sliding member. in lowered threaded open- 123. the sliding arms 16. The lower' end Vot the sliding member 'is provided with oppositely a-rhranged parallel depending lugs or arms 1T. and cach lug or arm is provided on its rear face with a projection 1S.

The slidingr member is, as before stated. arranged in the guideway, and the Vside walls of the guidewav are provided with inwardly extending longitudinal ribs l19, the said ribs engaging behind the sliding member to retain the same in place in the guidewav. A cover plate :2O is arranged over the guideway, and the said plate is held in placel b3' a screw 21, which passes through an opening in the cover plate and engages the opening of the lug 11. d i

A coil spring 22 is arranged between the lug :l1 and the lower end of the slot or recess 14, the said spring acting normally to pull the, sliding member upward. The sliding member is normalllv held. in the position 4of Fig. 2 with the cross .bar abovethe upper endof the extension 5, by" means of a latch or trip in the form of a sleeve or button, having each of its ends enlarged at 24 and '25 respectively, the latter forming a head for engagement by a striker, to be presently described. to release the sliding member.

The trip or latch is normally pressed towardtbe front wall of the casingf, bv

,means of va coil spring 26, the said spring being arranged between the cover plate 21 and the head of the trip, a portion of the spring being within the body of the trip.

latch passes through an opening The 4trip or QT in the reinforcing member 7, and the head 25 is inthe body of the casing 1, near the top thereof. The said Ireinforcing mem-l ber T is extended below the extension. as will be seen from an /inspection of Fig. 2, vand the enlargement 24 of the trip is in the shape of a cross head Whose ends engage above the projections 18 onv the lugs 17 to hold the osition.

The striker, beforementioned, comprises an angular head or hammer 28, on the upper end of a lever 29, which is pivoted at 30. to a.4 bracket arm 31,' in the lower end of the casing 4. A s'pringBQ is arranged at the lower end of the lever'below the pivotal connection 30 thereof andthe said spring 'n'ormallyracts to move the hammer or head Patented oet. c, 1914."
